TYPEWRITING-MACHINE To all whom t may concern:

Be it known that I., CORNELIUS 13.00E- ooRAN, a citizen of the United Statesresiding in borough of the BronX,.in the county of the Bronx, city and State of New York, have invented'certain new and useful Improvements in Typewriting- Machines, of which the following is aspeciiication. This invention relates to typewriting machines, and more espe'oiallyto'means whereby the beginning of the writing line may be varied. r VThe invention is herein disclosed as applied to an, Underwood typewriting machine having one form (somewhat modified) .adaptedtobe used in addressing envelops,-

in whichwork it is usually desired that the iirst line shall begin the farthestv to. the'left, the next line not quite soy far to the left, etc. To accomplish such variation in the beginning of the writing line, I have found it advantageous to utilize a margin-stop of the general type, indicatedy above, said stop having associated therewith, on the typewriter carriage, a releasable'margin-arresting 4leyer, these parts being well adapted to receive andresist the shock of arresting thetypewriter carriage. In Order to'cause the "desired variation of the point at which the carriage is arrested, I have found it advantageous tol provide that the margin-release lever may be variously positioned to coperate with variously located lugs upon the VI nargin-stop.

As herein illustrated, this varying of cooperation may be'effected by'operation of the line-space lever, andthe construction may be such that the line-space lever may be easily renderedjineffective upon the connections. This insures not only that the carl l riage mayvtravel uninterruptedly untilY arrested bythe right-handfinargin-stop, but that the parts coperating therewith may be made of any desired strength, since they may be of substantially the sameV strength and rigidity as those already? employed.

. ther features and advantages will hereinafter appear. [In the accompanying drawings,

chine, the revoluble: platen l is fast on an aXle 2 journaled in a vshift frame 3, formingl part of thecarriage 4. The platen l isy soV In the usual Underwood typewriting ma.-

adapted to be rotated by th'ej usual knob 5 or by the usualzline-spaoe lever 6, whichis pivoted upon the carriage at 7, and is adaptedvby means ofabell-crank arm 8 tO- diive a slide 9 to Vturn the platen l, bymean'sof the usual line-space wheellO, through the usual p awl 1-1. Y

An envelopy l2,.when passed around the platen, is held in position bythe usual devices (not shown),so that types 13 on the ends of type-bars 14 may print thereon the charactersone after another in addressing the envelop. .When `a-line `of writing has been finished, the typist actuates the linespace lever 6, thereby not only causing the yplaten to rotate but also causing the carriage 4 to return to the lett, under the con` tinued pressure upon the line-space lever, until a margin-release lever 15 brings lts lug16 against a lug 17, ot somewhat the `usual form, upon a margin stop 18, thus In order to enablethe margin stop to 'beY compact and strong enough to resist the blow of arresting the carriage, it comprises a barrel 2O partly embracing a shaft 21, and adapted to be held adjusted along the shaft by means of teeth 22, which form part of an arm 23 pivote'd at 24 upon a slidable mounting-25. Since the barrel 2O and the lug 17 are rigid with the mounting 25, the stop first holds the lug 17 in arresting position. The teeth 22 may engage with the usual teeth 26 cut upon the shaft 21, and to enable the margin stop to be released, may be swung out ol mesh by swinging .the arm 23 by means of the usual finger-piece 27. lllhenthe margin-stop has been adjusted by means of its handle 28, which is adapted to be gripped by the linger of the typist when another linger grips the finger-piece 27, the position at which it is set to arrest the carriage is indicated by the usual pointer 29, which ,overlies the usual scale-plate 30.

`According to the present invention, the

' margin-release lever has its lug 16 held in lever 15 down against a cam 32.

position to engage the margin-stop lug 17, because a spring 31 continually resses the it is desired to vary the vpoint at which the carriage is arrested by the lug 16 without shifting the margin-stop, the cam 32 may be rotated, with the result that, instead of holding the lug 16 in the position shown in Fig. 6, it will allow the spring 31to depress the lever .to carry its lug` 16 to the level of a sec-A ond 'lug 33, which is lower down on the same margin-stop and is in advance of the lug 17.V According to the present disclosure ol' the invention, the cam 32 is adapted to be rotated automatically by actuation Vof the linespace lever, and, for this purpose, the cam is fast to a shaft 34, which is valso 'fast on a ratchet wheel 35, said ratchet wheel being adapted to be turned intermittently by the line-space lever by connections which will now be described. These connections include a slide 36, which lies along the front part of the carriage, and which comprises ali-adjustable extension 37 adapted to be set so that it will normally lie almost( against y the line-space lever, with the result that when the line-space lever is actuated, it will carry along the extension 37, the slide 36, and cause a pin 38 upon said slide to turn a plate 39, journaled upon the shaft 34 and provided with a slot 40 in which the pin 38 is adapted kto ride. This slot 40 forms,

therefore, a cam by which the slide` 36 drives the ratchet wheel 35.

In theusual .Underwood typewriting machine, the line-space lever 64 has auniform throw, and the slot 40 and pin 38 are so adjusted with reference to the shaft 34 that the l-'ull stroke of the line-space lever, in the tion to causev the writing tobegin at the proper point in the third line of addressing an envelop. lnasmuch as rthe cam 32 can make a Vcomplete revolution, another actuation of the line-space lever will revolve it from the Fig. 9 position to the Fig. 1 position ready for the insertion of a new envelop.

The connectionbetween the plate 39 and the ratchet wheel 35 is effected by means of a pawl-42, which is adapted to be drawn back rearwardly over the ratchet wheelwhen the slide 36 is Vdrawn backwardly vbythe spring 43, which normally tensions it toi-the right. To hold the pawl 42 normally in position to engage the ratchet wheel, a light spring 44 fast upon the plate 39 overlies it. To enable the extension 37 to be'adjusted relatively to the slide 36, the `extension is formed as a slide plate running within channels 45 formed upon'the slide 36.. For convenience in slipping the extension 37 along 46V mounted on a spring 47, which is fast to the extension 37, said finger-piece being provided with a pin 48 extending rearwardly therefrom, and adapted to seat either in an opening 49, which holds the extension in position to be actuated by the line-space lever, or in an opening 50, which holds the extension 37 clear of the line-space lever, even at the limit of its throw.. This structure permits the iin'gerlpiece 46 to be utilized to actuate the slide for rotating the cam 32 directly, if desired, without `actuating the line-space lever.

The slide 36 itself lies behindthe usual liront bar 51 of the Underwood'typewriter carriage, and the connection between it and the extension 37 is formed by an angle plate 52 fast upon the slide 36, and carrying the secondary plate 53, in which the channels 45 areA formed. i To guide the slide36, it is provided with a pair of slots 54 and 55, which ride on a pairv of shouldered screws 60 and 61 threaded into the bar 51. The screw 61- may serve as an anchorage for the spring 43.

As is clearly shown in Fig., 1, the shaft 34V passes through the front bar 51 and is journaled thereonV in any suitable manner against sliding. This may be effected, as shovvn in F ig. 3, by providing the shaft 34 With a squared section 62 uponfvvhich the ratchet Wheel 35Y fits, so that the ratchet Wheel will lie close tothe rear face ,of the bar 51, While the cam 32 lies against the front face of said bar. The plate 39.may be journaled upon aneXteiision 63 of the shaft 34: and be held thereon by a suitable nut r64, which screws up against a shoulder 65 on the shaft 34. In order to enable the typist to see at a glance in what position the typewriter carriage Will be arrested, the releasing lever 15 ispro-V tive, independently of the travel of the carriage. e Y Y 2.
